M54HC4094

The M54/74HC4094 is a high speed CMOS 8 BIT SIPOSHIFT LATCH REGISTERfabricated with silicon gate C²MOS technology.

M54/74HC4094 has the same high speed performance of LSTTL combined with true CMOS low power consumption. This device consists of an 8-bit shift register and an 8-bit latch with 3-state output buffer. Data is shifted serially through the shift register on the positive going transition of the clock input signal. The output of the last stage (Qs) can be used to cascade several devices.

M54/74HC4094 Data on theQs output is transferred to a second output (Qs') on the following negative transition of the clock input signal. The data of each stage of the shift register is provided with a latch, which latches data on the negative going transition of the STROBE input signal. When the STROBE input is held high, data propagates through the latch to a3-state output buffer.

This buffer M54/74HC4094 is enabled when OUTPUT ENABLE input is taken high. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
